Replacement Core Support, Radiator and Condenser for 2003 Mazda Protege5

Radiator Core Support, Radiators, Condensers & Cooling Fans for Your 2003 Mazda Protege5

Restore front-end alignment and efficient cooling on your 2003 Mazda Protege5 with direct-fit core supports, radiators, condensers and cooling fans. Our OE-style and CAPA-certified parts ensure proper fitment, reliable airflow and robust protection for your engine bay systems.

Core Support: Alignment & Mounting

The radiator core support locates the radiator, condenser, fan shroud and often hood latch or headlight brackets. Worn or bent supports cause misaligned hood/fenders, cooling issues and increased vibration.

Our direct-fit replacements match factory mounts and geometry, restoring proper structure and fit.

Radiators & A/C Condensers

A robust radiator disperses engine heat while a properly-fitting condenser ensures your A/C blows cold. Damage from impacts, leaks or corrosion reduces cooling and can lead to overheating or system failure.

Choose OE-style cores built for correct thickness, hose locations and condenser mounting to ensure full function.

Cooling Fan & Shroud Units

The cooling fan (electric or mechanical) draws air through the radiator and condenser, especially when the vehicle is idle or working hard. A worn or non-working fan causes high engine temps, A/C inefficiency or damage in stop-and-go driving.

Install direct-fit fan assemblies with correct shroud curvature and OEM mounting points to keep your 2003 Mazda Protege5 running cool under all conditions.

Complete Core Support Assemblies

For full repairs after front-end damage, complete core support assemblies provide upper and lower tie bars, condenser brackets, radiator mounts and sometimes headlight or hood latch mounts. A full assembly restores structure and fitment in one step.

These assemblies are ideal when multiple components (radiator, condenser, bracketry) have been impacted or corroded.

Why These Parts Matter

Structural support and cooling system integrity go hand-in-hand. Replacing worn or damaged components helps prevent:

• Overheating caused by restricted airflow or leaks
• Weak A/C performance due to damaged condenser or fan failure
• Hood/fender misalignment from bent core supports
• Vibration, rattles or premature part failure from poor mounts

Signs You Need Replacement

• Coolant or refrigerant leaks; fins bent or corroded
• High engine temps at idle or slow speeds
• A/C blowing warm; cooling fan fails to engage
• Misaligned hood, fenders or grill; visible cracks or warping in the core support

Install & Fitment Tips

• Test-Fit Supports First: Bolt the core support in and verify hood/hood latch/fender alignment before final paint.
• Flush Cooling System: On radiator replacement, flush and refill with correct coolant mix.
• Evacuate & Recharge A/C: If the condenser is replaced, use new O-rings and recharge to specification.
• Inspect Fan Mounting & Wiring: Ensure fan spin clearance and proper plug connection for full cooling performance.
• Use New Hardware & Isolators: Replace any worn bolts, bushings or mounts to reduce vibration and prolong life.
